Irritator's skull is the most complete skull of any spinosaurid dinosaur ever found.1

Its name comes from the irritation scientists felt because fossil collectors had damaged and altered the skull before it was studied.1

A tooth from Irritator was found stuck in the neck bone of a pterosaur, showing that it ate pterosaurs, either by hunting or scavenging.1

Irritator had a thin crest on top of its head, and strong neck muscles were probably attached there.1

Its nostrils were positioned far back on its snout, not at the tip like in many other dinosaurs.1

Irritator lived in a coastal lagoon environment that was surrounded by dry areas.1

The fossil was originally thought to be from a pterosaur, then a maniraptoran dinosaur, before being identified as a spinosaurid in 1996.1

o botsitse

Dipotso tse di botswang thata ka ga Irritator

?How big was Irritator?

About 6 to 8 metres (20 to 26 feet) long and weighed around 1 tonne (1.1 short tons). It was one of the smallest spinosaurids.1

?What did Irritator eat?

It ate fish and other small animals, like today's crocodiles. A tooth was found stuck in a pterosaur neck bone, so it also ate pterosaurs, either by hunting or scavenging.1

?Why is it called Irritator?

Its name comes from the word 'irritation' because scientists were annoyed that fossil collectors had damaged and altered the skull before they could study it.1

?Did Irritator have feathers?

Nobody knows for sure. No fossil feathers have been found with Irritator, and most spinosaurids are not known to have had feathers.1

?Could Irritator swim?

It may have been semiaquatic, meaning it spent time in water. It lived in a coastal lagoon and probably hunted fish, like today's crocodiles.1

?Was Irritator bigger than T. rex?

No, it was much smaller. Irritator was about 6 to 8 metres long, while T. rex could be over 12 metres long.1

?Did Irritator have a sail on its back?

One possible skeleton suggests it had a sail, like other spinosaurids, but since only a skull has been found, the sail is a guess.2

?When did Irritator live?

It lived during the Early Cretaceous Period, about 113 to 110 million years ago.1

Mothubi wa ditlhamane

Tlhamane: Some people think Irritator was a fully aquatic dinosaur that only ate fish.

Boammaaruri: Scientists think Irritator was a generalist eater, catching fish and other small prey, and it may have also scavenged. It probably lived both on land and in water.1
